    Abstract: The system for producing non-blinding light from a fluorescent tube comprises a discharge lamp of which the cross-section area has the shape of an equilateral triangle with round edges. Through the invention not only is energy saved, but glaring light is made impossible, thus minimizing dazzling.

    Abstract: A handheld lamp is disclosed wherein the light source is a rapid pulse unconfined xenon arc tube containing more than three atmospheres of xenon gas pressure, and providing a selectable spectral output of ultraviolet, visible, or ultraviolet and visible wavelengths. The lamp contains a radiation guide for directing the generating light, the tip of which is maintained cool for effective use such as in curing tooth restorative materials. The lamp may be located in the power supply and light delivered through a flexible light pipe.

    Abstract: A device is disclosed for producing an electrical arc which is stabilized by a stream of metastable argon, or some other stabilizing gas. The arc may be employed to vaporize a sample material so as to produce light for spectroscopic analysis. The vaporization is rapid so that the constituents of the sample material can be determined very quickly and accurately. The arc is highly stable so that it operates without sputtering, dancing or showing other signs of instability. Thus, the results obtained with the arc are highly accurate and repeatable. The arc is produced between a cathode in one end of an arc chamber and an anode outside the opposite end of the chamber. The arc passes out of the chamber through an orifice in a gas shaping nozzle. Argon gas is supplied to the chamber through a plurality of gas inlets, which preferably are directed at angles having peripheral components so that a whirling motion is imparted to the gas as it enters the chamber. The gas is discharged steadily out of the chamber through the nozzle and toward the anode in a restricted, shaped and controlled amount, so that the gas plays in a sloped beam over the anode. The sample material to be analyzed is preferably contained within a cavity in the anode, which is heated to a high temperature by the arc, so that the sample material will be vaporized.
